Here is a chart of the doubles 00 thur 44. This is a list of the doubles that haven't been drawn in the longest time. (2012 or earlier.) The chart includes the 'sum' of each double. The Date is coded. D-12 is December of 2012. This chart lists the doubles that have never been drawn. The greyed out numbers have been drawn since I started this chart in Sept of 2015. (S-15 is Sept of 2015.)
The sums are color coded. Blue is low sums. Green is average sum. Yellow is high sum. There are 94 boxed numbers on my list out of a possible 360 boxed doubles.
